My research area is human-computer interaction (HCI) studying the interplay of technology with individuals, groups, and society. I study how people interact with information technology in their everyday life: how it affects multitasking, attention, mood, and above all, stress. Rather than bring people into a laboratory to study them, I go to where people are--the real world becomes a living laboratory.  Using precise objective measures, I found that  people's attention spans have been shrinking over the last 15 years.  I combine these measures with others to create a very detailed, comprehensive, and in-depth understanding of what people experience when they use computer technology.
